SGER: Amplification & Detection of Trace Quantities of Biological and Chemical Agents using High Surface Area Membranes and an Ultrafast Planar Array IR Spectrograph

特拉华州大学的John Rabolt教授和杜邦公司研发实验站的布鲁斯蔡斯博士正在开发一种便携式红外焦平面阵列光谱仪，用于实时检测气体中的化学和生物制剂。 该方法有可能在100微秒的时间尺度上提供红外吸光度信息。 通过静电纺丝产生的高表面积聚合物将用于浓缩痕量的有毒分析物。 该方法有可能简化和产生气溶胶液滴和颗粒的IR光谱，这些气溶胶液滴和颗粒由于其尺寸和/或透射率而不能在气相中检测到。 这种坚固耐用的仪器可以进行真实的实时采样，并将在国家安全、环境和工业过程监测中得到应用。 该项目中的一个特定目标分析物是沙林替代物。该奖项由NSF和情报界共同支持。数学和物理科学局的打击恐怖主义办法方案支持基础研究和劳动力发展方面的新概念，这些概念有可能促进国家安全。

Professor John Rabolt of the University of Delaware and Dr. Bruce Chase of Dupont Corporate R&D Experimental Station are working to develop a portable infrared focal plane array spectrometer for the real-time detection of chemical and biological agents in gases. The method has the potential to deliver infrared absorbance information on a time scale of 100's of microseconds. High surface area polymers produced by electrospinning will be utilized to concentrate trace quantities of toxic analytes. The method has the potential to amplifiy and produce IR spectra of aerosol droplets and particulates that cannot be detected in the gas phase due to their size and/or transmissivity. The rugged instrument can sample in real time and would have applications in national security, environmental and industrial process monitoring. One specific target analyte in this project is a sarin surrogate.This award is supported jointly by the NSF and the Intelligence Community. The Approaches to Combat Terrorism Program in the Directorate for Mathematics and Physical Sciences supports new concepts in basic research and workforce development with the potential to contribute to national security.
